Performance Simulation of Nanoscale Silicon Rod Field-Effect Transistor Logic

We have simulated the behavior of a rod shaped nanoscale ring-gated field-effect transistor (RGFET) using the PISCES-IIb[1] semiconductor driftdiffusion solver. The results from these simulations are used by a customized SPICE 3f5[2] kernel to simulate several simple logic gates. The usefulness of this kind of transistor is examined within the context of a selfassembling fabrication technique t...

Transport Simulation of a Nanoscale Silicon Rod Field-Effect Transistor

We have simulated the behavior of a rod shaped nanoscale ring-gated field-effect transistor (O-FET) using the PISCES-IIb[1] semiconductor drift-diffusion solver. The results from these simulations are used by a custom SPICE 3f5[2] kernel to simulate several simple logic gates.

Channel-Width Dependent Enhancement in Nanoscale Field Effect Transistor

We report the observation of channel-width dependent enhancement in nanoscale field effect transistors containing lithographically-patterned silicon nanowires as the conduction channel. These devices behave as conventional metal-oxide-semiconductor field-effect transistors in reverse source drain bias. Reduction of nanowire width below 200 nm leads to dramatic change in the threshold voltage. D...
